Agreed.  It's definitely NOT the case that the silent switch will
disable fail-on-error.

Example:

  $ cat Makefile
  all: ; false

  $ make --version
  GNU Make 4.4
  Build for x86_64-pc-linux-gnu
    ...

  $ make
  false
  make: *** [Makefile:1: all] Error 1

  $ make -s
  make: *** [Makefile:1: all] Error 1

You can see that even with -s we still get a failure.

You will have to keep looking at your makefiles to figure out what the
real problem is.  I agree with Kaz; you should search your makefiles
for places where you try to parse MAKEFLAGS since the contents of
MAKEFLAGS changed in 4.4.
